GLASGOW SOCIETY OF FIELD NATURALISTS. 31 



By Mr. A. Watt. — A number of plants collected near Lai-gs, 

 including the mosses Hypnuvi Schreberi, Mnium serratmn, and 

 Brywm Zierii, all in fruit ; also the rare grass Avena puhescens. 



By Mr. P. Cameron. — Hemichroa, luridiventris, Fallen, a rare 

 saw-fl.y, captured in the larva state at Locli-Lomond, and bred last 

 month. This is the larvse mentioned in last year's " Transactions," 

 p. n , under the name of Camponiscus Healaei, Newman. He also 

 gave an account of an entomological tour to Bannoch this month. 

 Whilst there, the weather was on the whole favourable, but unfor- 

 tunately insects of all orders were very scarce, and he had not been 

 able to make many additions to his collection. In particular, he 

 was disappointed in procuring only five specimens of Pine Saw- 

 flies (namely, three of Lophyrus pini, L., and one each of L.pallipes, 

 Fall,, and L. virens, Klug), after exploring nearly the whole of the 

 Black Wood specially for them. Two saw-flies new to Britain 

 were captured (probably more, as the whole of the captures had 

 not yet been examined). These are : — Poecilosoma pulverata, Betz, 

 one of the finest species of the genus, having the feet pale red, with 

 the abdominal segments faintly banded with white ; and Taxonus 

 coxalis, Klug, which has segments six to eight of the abdomen red. 

 The only other noteworthy saw-fly as yet named is Croesus varus, 

 YilL, which is, rightly or wrongly, described by Stephens ("111, 

 Brit, Ent.," vii., 39), but is omitted by Mr. F. Smith in his 

 *' Nomenclature of British Hymenoptera." The discovery of the 

 species at Rannoch places the fact of its British nativity beyond 

 dispute. 



On the male catkins of the oak were found, at Dall and 

 Kinloch-Bannoch, the galls of Andricus quadrilineatus, Hartig, 

 and A. amenti, Gir., neither of which have been recorded as 

 British. 



He also exhibited the galls and insects of Andricus ramuli, L., 

 which are known as the " cotton gall of the oak," so called from 

 the long white fibres which are attached to the gall proper, giving 

 it the appeai'ance of tufts of cotton. Another gall, also new to 

 the British list, had been found sticking out of the leaf buds, but 

 as only inquilines had been reared the species could not be properly 

 identified. 



EXCURSION. 



Gouroch and Clock. — Mr. Gregorson reported that the excui-- 

 sionists had a pleasant ramble in the glens and on the hill-sides,
